A note on the multivariate miser for balancing experiments

The MISER criterion for pre-experiment balancing of experiments that will be analyzed by the analysis of covariance was proposed by Press (1987). The idea was to minimize, over all designs, the inflation produced by design imbalance (inequality of cell covariate vectors) , of the average standard errors of contrasts. In this note we consider the balancing problem in the case of multiple response experiments, and we show that under certain reasonable assumptions, the multivariate result is analogous to that in the univariate case.     

EFFICIENT MODULAR IMPLEMENTATION OF BRANCH-AND-BOUND ALGORITHMS*

This paper demonstrates how branch-and-bound algorithms can be modularized to obtain implementation efficiencies. For the manager, this advantage can be used to obtain faster implementation of algorithm results; for the scientist, it allows efficiencies in the construction of similar algorithms with different search and addressing structures for the purpose of testing to find a preferred algorithm. The demonstration in part is achieved by showing how the computer code of a central module of logic can be transported between different algorithms that have the same search strategy. Modularizations of three common searches (the best-bound search and two variants of the last-in-first-out search) with two addressing methods are detailed and contrasted. Using four assembly line balancing algorithms as examples, modularization is demonstrated and the search and addressing methods are contrasted. The application potential of modularization is broad and includes linear programming-based integer programming. Benefits and disadvantages of modularization are discussed. Computational results demonstrate the viability of the method.     

MODELS OF PARTS-ORIENTING SYSTEMS*

An analytical model to estimate, evaluate, and compare the behavior and performance of parts-orienting systems for automated manufacturing systems is developed. The model can be applied to parts-orienting systems for both traditional series-structured manufacturing systems and nontraditionally structured flexible manufacturing systems. Numerical examples are given for typical system configurations such as the pure series system, the pure parallel system, and the pure feedback system.     

公司债持有人与公司股东之利益冲突

公司债券是资本市场的重要融资工具,我国经济发展急需公司债的相关法律制度。对公司债制度的法律设计至为重要的是研究公司债的参与人,以及他们之间的利益诉求和利益冲突。本文试图说明公司债参与人中,公司债持有人与公司股东有着不同的利益冲突。本文首先介绍了传统的公司债持有人与股东利益冲突理论学说,然后从法经济学视角,分析公司债持有人、股东的利益冲突,并辨析了双方的损益情况。本文借公司债持有人与公司股东利益之分析,以期为公司债法律平衡机制的设计提供理论前提。     

城乡统筹中农地利益均衡与农民土地权益保护

城乡统筹发展中存在农地利益失衡的现象,损害了农民土地权益,影响了城乡统筹和谐发展。农地利益均衡存在农地制度不完善,政府规制不健全,农地市场不规范,利益诉求机制不完备等制约因素。为此,应完善农地法律制度,从法律上保护农民土地利益;健全政府规制机制,让政府能有效保护农民土地利益;构建农地市场机制,让市场为农民提供应得农地利益;完备农民农地利益诉求机制,让农民自己能有效维护农地利益,从而形成系统的农地利益均衡机制,有效保护好农民土地权益,和谐推进城乡统筹发展。

本文在作者以前提出的用模态参数识别技术进行挠性转子动平衡的方法的基础上,提供几种实用的识别中的数据处理方法。旨在提高识别算法的稳定性以及解决测点较少时的处理方法。模拟转子试验证实了方法的可行性。     

试析均势与均势功能的维持

随着近代国际体系的形成,均势原则作为一种国际关系发展的规律和政治现象日益凸显出来,并成为一支重要的国际关系理论和颇具影响力的外交战略。从本质上均势自然或不自然地遵循着两项命题假设,并大致形成了三种概念解释或理论假说,状态机能说、政策动机说与权力关系说。威斯特伐利亚体系和维也纳体系作为传统均势的典型模式,从一个侧面揭示了均势理论的结构性缺陷和弊端,即所谓"制衡难题"。尽管如此,均势原则仍不失为国际政治的一般原理和现代国家体系的基本原则。     

Positivity conditions for stochastic state space modelling of time series

This short paper clarifies some aspects of the balancing method for state space modelling of observed time series. This method may fail to satisfy the so-called positive real condition for stochastic processes. We illustrate this by theoretical spectral analysis and also by simulating univariate ARMA (1,1) models.     

统筹城乡发展中的人口政策研究述评

认真研究统筹城乡发展中的人口政策问题对统筹城乡发展和统筹解决人口问题都具有非常重要的意义。统筹城乡发展中的人口政策研究涉及到了统筹解决城乡人口数量、素质、结构、分布的协调发展问题．包括了人口与计划生育、人力资源开发与教育、社会保障、就业与劳动保障等方面的内容。目前较多成果集中在人口政策对统筹城乡发展的重要性、意义、作用路径与方式等方面。未来还需要在对人口政策体系进行调研的基础上进行全面系统地研究。文章最后提出了系统研究统筹城乡发展中的人口政策内容。     

宪法中的法益衡量:一种可能的重构——以阿列克西的理论为思路

在宪法上,法益衡量的地位较之于其在民法上的地位更为显要,其本身作为一种面向现实且围绕规范而展开并形成判断的方法,既是对法律形式主义的反动,也是对现实主义阵营中的某些虚无论调的克服。但作为含有价值判断的一种方法,衡量在各国学术界也颇遭争议。对此,德国当代著名法学家罗伯特.阿列克西则从规范结构的视角为衡量提供了一个没有矛盾的明晰概念和精致的法结构,在这种结构框架中,实体的内容是借助法律论证理论及工具加以证立的。由于这种衡量理论乃以规范分析为进路,并能容纳其他法学方法,为此在一定程度上消除了对衡量的有关质疑,并在重构衡量理论,寻求衡量正当化的进路上具有重要意义。
